Definitions
- the present invention relates to treatment of organs in a diseased patient.
- the method of the present invention is characterized by direct joining of the arterial system of a host animal with the arterial system of a patient animal to provide for relatively unobstructed homogeneous blood flow through the arterial system of the patient. If necessary, the blood flow to or from the patient may be restricted to attain balanced flow between his arterial system and that of the host.
- FIG. 1 is a top view showing the femoral triangles of a host and patient with the arterial systems thereof connected;
- FIG. 2 is a diagramatic view of the method of the present invention.
- the method of present invention may be utilized to join the arterial system of human beings or animals together for regression or resolution of a disease process or in experimenting therewith to better understand the etiology thereof.
- a disease processes well understood is diabetes mellitus, wherein the patient is typically treated with controlled dosages of insulin naturally produced by the non-diabetic host, thus minimizing or even eliminating the necessity of treatment with exogeneous insulin.
- Patients who may be treated with the present invention are those with diseases not so well understood such as those with advanced metastatic carcinoma, to seek regression or resolution of the disease from the affect of the physiologic mechanisms of the host.
- the method of the present invention may be utilized in treating diseased animals such as human beings and that the reference herein to the patient and contemplate respectively, a diseased animal and reference to a host contemplates a healthy animal.
- the method contemplates that a host will be selected having a blood fully compatable with that of the patient depicted at 12 in FIG. 2 and, of course, in a method involving human beings, giving his consent to the procedure.
- the host and patient may then be positioned adjacent one another, as for instance, lying supine or reclining in a dual contoured chair as depicted at 14 in FIG. 2, and spaced only a few centimeters apart to minimize the length of graft necessary to join their arterial systems.
- the monitors are then established as depicted at 16, including arterial pressure (CVP), Swan-Ganz catheters, or any other parameters, the monitoring of which is desired, once the host has been selected. Blood chemistries, gas studies and all related base line studies desirable are conducted.
- the anesthesia may be local as depicted at 20 (FIG. 2).
- vertical incisions are made over the femoral triangles 11 and 13 of the host and patient as shown at 22 (FIG. 2), to expose the common femoral arteries from inguinal ligament 17, including bifurcation superficial and deep.
- Both patients are given 5,000 units of Heparin solution No. IV.
- Vascular clamps 19 are then applied to the common femoral arteries 15 and 17 at spaced apart locations to halt blood flow.
- the common femoral arteries 15 and 17 of the host and patient are then transected at points between the clamps 15 and 17 to expose open proximal and distal ends 21 and 23, respectively, of the host artery 15 and the open proximal and distal ends 25 and 27 of the patient artery 17.
- Anastamose gortex grafts about 8 mm. in diameter and of sufficient length to lead from the proximal end 21 of the host artery 15 to the distal end 27 of the patient artery 17 and, likewise, from the proximal end 25 of the patient's artery 17 to the distal end 23 of the host artery 15, are then selected.
- regulators generally designated 35 and 37 may be installed in the respective grafts 31 and 33 for purposes which will appear hereinafter.
- the graft 31 is sutured on one end to the proximal end 21 of the host's artery 15 and on its opposite end to the distal end 27 of the patient's artery 17 to thus form a shunt from the arterial system of the host to the patient.
- one end of the graft 33 is sutured to the proximal end 25 of the patient's artery 17 and the opposite end thereof is sutured to the distal end 23 of the host's artery 15 to thus form a shunt from the patient's arterial system to the host's arterial system.
- regulators 35 and 37 are optional and may be of the character that include respective flow meters 41 and 43 to indicate the blood flow rate from the host to the patient and from the patient to the host, respectively.
- Such regulators 35 and 37 may include flow control valves operated by manual stems 45 and 47, respectively, such that the blood flow rate through the respective grafts may be adjusted independent of one another.
- the vascular clamps 19 may be removed from the arteries 15 and 17 to thus establish blood flow from the host to the patient and from the patient to the host and the respective flows may be monitored as depicted at 26 (FIG. 2) by the respective flow meters 41 and 43. It is desirable to maintain such flows evenly balanced to thus arrive at a homogeneous blood mixture and avoid depriving either the host or the patient of blood volume. Such balance may be established by adjusting the valve stems 45 and 47 as dictated by the respective flow meters 41 and 43. It will be appreciated that in the event of any disturbance, the valves 45 and 47 may be closed rapidly to terminate blood flow.
- fascia and skin may be closed around the grafts 31 and 33 and such sleeve (not shown) sutured to the skin to maintain sterility.
- the combined circulation may then be continued for the desired time period, all the while maintaining blood flow through the grafts 31 and 33 equal and monitoring the meters 41 and 43 to detect any clotting within the grafts, sepis, or any other indication of irregularities.
- the host and patient are re-prepped, drapped, anesthesized, the respective wounds opened and Heparin administered.
- the vascular clamps 19 are then applied simultaneously to the proximal ends 21 and 25 as well as the distal ends 23 and 27 of the respective arteries.
- the grafts 31 and 33 are then removed and end to end in anastomosis performed.
- the wound is then closed as depicted at 28, and both the host and patient tested for any irregularities and the base line studies compared.
- the method of the present invention is relatively safe for the patient. Also, there is little likelihood of the host contracting cancer or other non-infectious diseases from the patient. Morbidity and mortality of this surgical procedure is low since the exposure and procedure is relatively simple and no vital organs are directly involved. Since the blood serves to mediate and communicate to the cellular level all the physiologic responses of the organism, all cells, both normal and abnormal, are exposed to all the physiologic responses of both host and patient.
